While teams could all talk to potential free agents from other teams the last couple of days and business in the NFL was ongoing for 2019, Wednesday -- Wednesday at 1 p.m. Arizona time, to be more specific -- is the big day. The new league year arrives.

This means the trades that have been agreed upon can finally be consummated. Free agents-to-be who have talked to other teams can finally sign contracts. Teams must be compliant with the 2019 salary cap (which is $188.2 million) by the offseason rules, which means a team's top 51 cap numbers of the up-to-90 on the roster must be within that number. (Once we get to the first week of the regular season, that's when every player on the roster, from the active 53, practice squad and injured reserve must all be able to fit under the cap.)

That doesn't mean all the free agent news we've heard about for two-plus days suddenly becomes finalized. There are physicals to pass -- which is always key, ask Bashaud Breeland from last year -- and contracts to finalize and, of course, sign. But this is where things really start moving forward for the new season.

Oh, and Oklahoma's pro day is today too. The draft hasn't gone anywhere either, even with all the free-agent talk.
